DISPLAY-RACK.

Specicationiof Letters Patent. Application sied August is, 1909. serial No.

To all whom it may concern:

'Be it known that I, VooDronD SHANNON, a citizen of the United States, residing at Louisville, in,v the county of Jeffeion and State of Kentucky, have invented certain new and useful Improvements in Display- Racks, of which the following is a specication.

The present invention relates to display racks" of that type intended for displaying mattresses, and has for its purpose to provide such a device of knock-down construction, and. which when assembled maybe readily transported from place to place.

The essential purpose of the invention is in providing the display rack with carriages with means for permitting their withdrawal for almost their full length for placing in position the springs or mattresses to be displayed, or for removing them, said carriages being adapted to slide inJ and out to exhibit the goods.

The Ifurther advantage of the construction .is such that the supports or tracks for the .carriages may be adjusted relatively to each other so that the highest box mattresses or the smallest springs may be readily accommodated within the minimum of space.

With thse as the special advantages the invention embodies other points of novelty which will be pointed out in thecourse of the following extended description and set forth in the appended claims.

In the accompanying drawings which showthe preferred embodiments of the inventionz-Figure 1 is a perspective View o'f the display rack complete. Fig. 2 is a horizoutal sectional View of a carriage and guide rail, Fig. 3 is a diagrammatic illustration showin they disposition of the corner posts of the rame, Fig. 4 is a detail .view showing the disposition of the slots in the forward and rear corner posts, Fig. 5 is a transverse sectional View taken along the line 3 3 of Fig. 2, looking in the direction of the arrow, Fig. 6 is a front elevation of a guiderail and a forward end of a carriage, Fig. 7'is a perspective View of a modified form of dis-A play rack, Fig. 8 isa horizontal Sectional view correspondingto lthat shown in Fig. 2, Fig. 9 is a diagrammatic view corresponding to Fig.'3, Fig. 10 is a view corresponding to Fig. 4, and, Fig. 11 is a transverse sectional view taken along the linee-,+5 of Fig. 8, looking in the direction of the arrow.

.tions it will be observed e., their grooved portions are turned out- 65'v wardly, while the corresponding portions of the end bars ,thereof are turned inwardly. They are assembled in this relation by the corner plates 5. Connecting the upper and lower sections are the disposed in precisely that manner shown in Fig. 3; and for securing the same in position a plurality of 4corner platesl 7 are provided. The supporting framei-s fitted with casters 4 whereby the display rack may be 75 transported about the room.

The several parts justl enumerated constitute the frame structure and their manner of assembling is such-that the several parts constituting the same connected, to effect threaded bolts 8 Structure intact. The opposite -faces of the corner posts-f5 and the corresponding portions of posts 6- are each provided with of peculiarly shaped slots 7'., ing substantially a circular which ordinary screw are used for holding the a plurality dinary key-hole extension projects circular opening as display cabinets of diametrically from the is the case in mattress a known type, and the disadvanta es of which type will be re- 95 ferred to hereinafter. From the illustrathat the slots in the forward corner posts are `arranged in substantially vertical position and with their enlarged or circular portionsdisposed to the 10C j rear, while on 'the rear posts the tangential portions of the slots are disposed horizontally and ywith the circular or enlarged open- I ings toward the top. relative arrangement clear. c

The function of-'the slots is that of provThe advantage of this viding a means for adjustably and securely sup orting the several guide rails or tracks there are two for each mattress 1510 8 o whic angle bars of which the nucorner posts 5 and 6 70 are adapted-to be disthe realt` 85 each slot be-xit opening and" having a narrow extension projecting tan- 'i gentially therefrom as distinct from the or- 9@ slots wherein the narrow will presently be made supporting carriage. Each of the tracks S comprises an angle har on the vertically disposed portion of which and at each end is a headed stud or bolt 92 the purpose wher-eel being to engage within the slots T will be obvious by reterenceto Fig. l. The heads ot' the bolts 9 are such as will readily permit their inse tion within the circular opening of the slot, whence the shank portion oit' the boltsI may be brought within the tangential groove. And by reason of this manner ot connection and having the slots ot the jtront and rear corner posts in right angular relation, there is allowed some spring 'if the frame body, and ease in ndjnsting the spacing ot' the guide rails tor the carriages. Ylhis peculiar manner o1" connecting thegnide rails as compared to the .case wherein the key-hole member is adopted is .tnrther useful in that in the present instance the stads or bolts engaging the tangential portions ot the rear slots will 'prevent any tendency ot' the tracks to tilt when the carriages are. distended, while in the latter case the withdrawn carriage has a tendency to liit the rear ends ot the guide rails by virtue ot the key-hole slot connection. The horizontal portions of the guide or supporting' rails 8 constitute the tracks proper and at their forward ends they have jonrnaled therein each a roller 10 on which the sliding' carriage is adapted to travel.

The mattress supportingcarriages are likewise ot angle iron construction and comprise a framework et side bars 11, end bars 12, cross bars 1? and three or more tensioning-j rods 14e. The tensioningl rods 1l are rigidly secured to the forward angle bar 12 but have spiral springs 15 connecting with the rear angle bar.

llhe sidebars 11 of each carriage are disposed opposite to the tracks 8 whereby the latter provide.4 a support for the former shown in Fins. 1 and 5; and to readily permit the sliding; movement of the carriage upon the tracks the carriage is provided with a pair ol rollers 1G jonrnaled within the side bnrs 1l near their rear ends. lt will thns be seen that with the rollersl 1() and 16 cooperating' in the manner shown in Fig. 2, the mattress supportinev carriages may be readily ref-.iprot-ated in the manner desired and withifithe inininnnn amount oi" friction. To prevent thc weight oit the mattress or other article. supported upon the carriage 'from tilting`- the latter when it hasy been withdrai'vn, 'the rear anglel bi1-r ot the carriage is cut-away to provide i1 pair ot lugs or stops l which will engage with the underside of the tracks S when a carriage is drawn to such position as mentioned. The cut-away portion of the bar 12 provides they clearance tor the track S, as shown in Fig. 5. And to prevent. theI -arriage being' moved too far within the trame the t ront bar 12 ot the frame is of such width as to. engage with the forward ends of the track members 83 in the manner shown in l11 ig. (S. Referring to the alternative striiictnre of display cabinet which l have disclosed and which may be preferred` under certain con.- ditions it may be stated thatthe structure is generally of the forni ot'. rack above described. rilhe structure now under consideration comprises a supporting trame in lall respects similar to that described of Fig. 1 and need not 'therefore be described here.v

The ditlerenees lie only in the carriage and track construction to wit: To the under side and at the rear end of each track 8 there is provid'ed'an angle piece 18 which constitutes a stop tor a projecting piece 19 of which the'ii, are two fixed to each carriage. The purpose ot lthe .members 18 and 19 iis to limit the return movement of' the. cari" ringe; and the member 19 is farther serviceable in that -it prevents the carriage being" withdrawn too tar, in which event the stops 19 engage with the rollers 10. In the present instance, the front and rear angle bars 2O ot the carriagesare cut-away as shown at 21 to aline with the grooved surface of the angle bars 11.

1While I have shown and described the details of my invention I would notwish it understood that l have limited myself to the precise struct-ure shown7 since it may in certain instances be advisable to make certain changes which will better adapt the invention to the purpose in view; insteadl reserve the right to make suchehanges without departing from the spirit of the inventiony in question and limit myself only to such disclosures as are made in the prior art to which this invention pertains.

Having thus described my invention,A what I claim as new therein and desire to secure by Letters Patent7 is 1. A` display cabinet comprising a frame, slots formed in the frame at its front and rear ends, said slots being respectively disposed in relatively vertical and horizontal positions, tracks provided with members adapted to tit within said slots whereby to dctachably mount the same on the frame, a carriage mounted to slide on said tracks7 said horizontal slots adapted to prevent tilting ot the rear ends of said tracks when the carriage withdrawn; and means for limiting the sliding' movement ot' said carriage.

vjt display cabinet comprising a trame ot :l gie bars of knock-down construction, horizontally disposed slots formed in the rear vertical posts of said frame, vertically dispf sed slots formed in the front corner posts of the trame, tracks comprising angle bars provided with headed studs adapted to tit within the slots of the corner posts whereby said tracks are detachably mounted in the traine, carriages mounted to slide on said tracks, and means for limiting the slid?Y construction, slots formed in the corner posts of sa'id frame, said slots comprising each ak circular ospening having a tangential eXtension, the ots of the'rear corner posts being horizontally disposed, the slots of the front corner ostsbeing substantially vertically disposed track members 'comprising angle bars having headed studs adapted to itand lock within said slots whereby to adj ustably and detachably support the tracks within theframe, carriages mountedto slide on said tracks, means preventing the tilting of the carriages when the same are withdrawn, land means for limiting the sliding movement of said carriages.` 7
